20 Claims.

This invention relates to improvements in machines for applying strips of material to curved surfaces, and is directed more particularly to a device for covering the outer or working surfaces of drawing rolls for spinning machines with parchment paper or other suitable materials.

Another object of the invention is the provision of a machine for applying working surfaces having certain characteristics to drawing rolls, said surfaces being uniform on all drawing rolls passing through the machine, and thereby imparting constancy to the products of the drawing frames or the like in which said rolls are used.

A drawing roll consists of a shaft usually carrying two drum or solid cylindrical portions spaced apart from each other. Another object of the invention is the provision of a machine for applying strip material to the circumferential surfaces thereof, starting the strips in axial alignment with each other on the two surfaces and ending them at other points also in axial alignment with each other.

A further object of the invention is the provision in a machine of the character described, of rolls of material and means for applying adhesive to said material before it reaches the drawing rolls to which it is applied.

Yet another object of the invention is the provision of a machine for applying working surface materials to drawing rollers, said machine operating in definite cycles sequentially following each other.

A further object of the invention is the provisionof a machine of the character stated, in which trackage is provided for a plurality of drawing rolls to be covered and means for cyclicly releasing said rolls to the covering mechanism.

Another object of the invention is the provision in a machine of the character stated, of pneumatic means for starting surface strips onto said rolls, means for cutting said strips after they have started onto said rolls to insure the application of a predetermined length thereto,

and pneumatic means acting upon the trailingedge of said strip to facilitate the finishing off of the same.

Another object of the invention is the provision. in a machine for applying working surfaces to drawing rollers in which means is provided for successively feeding drawing rollers into the machine, and in which means is provided for halting the operation of the machine 1941, Serial No. 397,036

after the last drawing roller of a series has been covered.

Other objects and advantages of the invention will be apparent to those. skilled in the art upon a perusal of this specification.

Drawing rolls Drawing rolls (sometimes called top rolls) are used in connection with spinning, drawing, weaving and other textile machinery. An example of this use is in connection with the so-called French system of drawing in which wool in a dry state is prepared for the spinning frame.

Over the years many materials have been tried for forming working surfaces ondrawings, and it has been found that the most practicalmaterial for this purpose is parchment paper which up to the present time is applied to the surfaces of the rollsv by hand.

The machine The applying of strips of parchment paper or any other materials to the surfaces of drawing rollers is a tedious process as extra care must be taken to insure the uniform and proper application. Contrasted with this, our new and improved machine performs the operation automatically.

The machine may be set to apply a predetermined given length of material to each cylindrical portion of each roll assembly. The inner ends of the material are started onto the roll members in alignment (axially) with each other, and the outer ends are finished off in alignment with each other, pneumatic means aiding in this performance. The strip materials are carried in the machine in the form of rolls, and the strips are severed from the roll after their inner ends are started onto the surfaces of the drawing rolls. The machine includes means for applying a uniform coating of adhesive to the strips before they reach the drawing rolls. The machine operates cyclicly, and. as soon as one drawing roll has the material applied thereto it moves out, and a succeeding one is fed into position to receive its material, etc.

The machine, therefore, applies the material rapidly and with absolute uniformity, and the drawing rolls treated thereby impart the maximum. uniformity insofar as results are concerned in drawing and spinning operations.

Figure 15 is a view of a drawing roll before being covered; and a Figure 16 is a View of a drawing roll after being covered.

Referring to the drawings, the base 20 provided with suitable supporting legs forms a support for the mechanism.

The motor 23 secured to the base 28 carries a stepped pulley. A reduction gear 25, also secured to the base 28, has a shaft 26 projecting therefrom and carrying a pulley 27. A belt 28, engaging the smaller step of the pulley 24, drives the pulley 21. A shaft 29 extending from the reduction gear (Figure 5) is, due to the gearing in said reduction gear, driven at a reduced speed and carries a sprocket 38. A sprocket 3| (Figures 2 and 8) is carried by a cross-shaft 32. The shaft 32 is supported in a bearing 33 in the side'member 34 and a bearing 35 in a side member 36'. The sprocket 3| forms a working fit on the shaft 32; a suitable hub 31 may be formed integral with the sprocket 3|. I

About the sprocket 3| is a collar 38 which is keyed or otherwise fixed on the shaft 32. A shear pin 39 extends axially through the collar 38 and the hub 31 and is adapted to shear off when a load greater than normal is imposed on the mechanism.

A roller chain 48 extending around the sprockets 38 and 3| drives the shaft 32 in the direction indicated by th arrow when the motor is running. A gear 4| is keyed or otherwise fixedly secured to the shaft '32 and meshes with a gear 42 carried on the shaft 43 which will presently be described.

The shaft 32 also carriesa pinion 44 which is secured in fixed relation on the shaft by means of a set screw 45 in the hub 44 thereof. The pinion 44 meshes with a gear 46 mounted on a shaft 41 which will presently be described.

- Between the bearing 35 and the pinion 44 is an outboard bearing 48 carried on an upright member 49 mounted on the base 20. A star wheel actuator member includes a solid disc-like portion 58 and a cut-out portion 5| spanned by arms52 and 53. A roller 54 is pivotally supported adjacent to the outer ends of the arms 52 and 53 by means of a shaft 55.

The actuator member has a hub 56, and set screw 51 is provided for securing it in fixed relation to the shaft 32.

The shaft 32 also carries an index cam. 58, an air control cam 59, and a second air control cam ||5, all of which will presently be described in connection with parts which they control. The side members 34 and 36 are secured in fixed space relation to each other by a plurality of spacers 66 and thereby form a rigid frame.

A bearing 6| in the side member 36 (Figure 7) has journaled therein a stud shaft 62, the outer end of which is stepped and designated by the numeral 63. The stepped portion 63 carries a key 64 and has mounted thereon a star wheel 65. This star wheel, as can be seen in Figure 1, has six radial'slots 66 formed therein with curved surfaces 6'! therebetween and adapted to form working fits with the disc-like portion 50 of the ac-' tuator member.

The star wheel 65 is held on the shaft 63 by means of a cap screw 68 with a washer 69 therebetween. The stud shaft 62 has formed integral therewith a hub portion 18, a flange TI and a boss 12.

A turret plate 13 is mounted on the boss 12, and a gear 14 is mounted on the hub 10 by means of screws 15 passing through the plate 13, the flange II and into the gear 14. The form of the turret plate will be more fully described in connection with the description of Figure 6.

A shaft 16 has one end-thereof journaled in a ber 34. A shaft 19 has a portion of reduced diameter journaled in the bearing 18. A shaft 19 has a central hole therein carrying a bushing 8| which forms a bearing for the shaft 16. The right end of this shaft is seen in Figure 7 and has secured thereto a gear 82 which drives the shaft I6, as will hereinafter be described.

A hub member 83, in alignment with the shaft 79 and mounted on the bushing 8|, carries a gear 34 of the same pitch diameter and number of teeth as that of the gear 14. A flange 85 is formed integral with the hub 83, and a turret plate 86 is mounted adjacent to the flange 85; the gear 84,

the flange 85 and turret plate 86 being secured together with screws such as the screw 15 previously described in connection with the turret plate 13'. Referring now to Figure 6, the turret plates are identical except that they are rights and lefts and the turret plate 86 is shown in detail in this figure. There are six stages, each of which is defined by a radial slot Blformed in the plate to freely accommodate the projecting ends of the drawing r011 shafts, the end of the slot nearest the center being rounded to match the shaf of said drawing rolls 7 The edge 88 of the slot 81 extends outwardly and when a stage is in'position to receive a drawing roll from the feeding device (to be presently described) the edges 88 in the two turret plates provide slanting surfaces down which the drawing roll may roll with the outer ends of its shaft engaging the slots 81. The edges 89' are foreshortened and the corners.

presently described.

Referring back to Figure 7, the shaft 16 has keyed thereto rollers 99 and 9|, the peripheries of which are serrated or fluted. These rollers are preferably made integral with a hub 92 which is keyed to the shaft by means of a taper pin 93.

A bearing member 94 adjustably secured to the side member 36 by bolts 96 forms a support for one end of a shaft 95, and a similar bearing 91 secured to the side member 34 by means of bolts 98 forms a support for the other end of the shaft 94. A gear 99 is secured to the shaft 95 by means of a set screw I99 and meshes with the gear 14. A second gear I9I secured to the shaft 95 by means of a set screw I92 meshes with the gear 84. The gears 99 and I9I are of the same diameter and pitch, therefore when the star wheel 65 is moved one step the turret plate 13 is also moved one step. The turret plate 86 is likewise moved one step through the medium of the gear 14, the gear 99, the shaft 95, the gear I9I and the gear 84.

The gear 82, which drives the shaft 16 and the rollers 99 and 9| keyed thereto, meshes with the gear 42, previously described (see Figure 2).

The shaft 43 which carries the gear 42 is a stud shaft carried by a pivoted arm I93 (Figure '7), the upper end of which is journaled on the reduced portion 89 of the shaft 19 and the lower end of which is engaged by a screw passing through a slot I95 in the side member 34.

. This enables any desired adjustment of the gear 42 relative to the gear 4| and the gear 82 to be made.

The gear 4I, referring for the moment to Figure 6, has a number of its teeth cut away down to the root diameter thereof and thereby drives the gear 42 (Figure '7) which meshes therewith, during a definite portion of its cycle.

Referring now to Figure 2, the gear 42 is engaged by a plunger member I96 supported in a block I91 to prevent it from rotating in a clockwise direction. However, the plunger freely permits the gear 42 to be rotated in a counterclockwise direction.

Referring again to Figure 8, the upright member 49 also carries a bearing I98 which supports the shaft 41. The shaft 41 carries a sprocket I99 and a roller chain I I 9 embracing the same drives a sprocket II I on a shaft II2, supported in bearings H3 and H4 formed in the side members 36 and 34 respectively.

An idler II6 engages the chain II9 for maintaining the same taut.

The shaft II2, referring also to Figure 10, has keyed thereto a gear II1 adjacent to the bearing I98 and a second gear II8 adjacent to the bearing II 4. The side member 34 has formed therein a bearing I I9 in which a shaft I29 is journaled, one end of said shaft carrying a flange I2 I. The other end of the shaft I29 has secured thereto a pinion I22 which meshes with the gear H8.

The shaft I29 has a tapped hole I23 formed therein, and a cam I24 is secured in abutment with the flange I2I by means of a cap screw I25 and a washer I26.

The side member 36 has a bearing I21 formed therein in alignment with the bearing I I9.

A shaft I28 is journaled in the bearing I21 and carries on one end thereof a pinion I29 which meshes with the gear II1. On the other end of the shaft I28 is secured a sprocket I39. The

pinions. I22 and I29 are of the same diameter and the gears I I9 and; II] which respectively drive these pi'nions are of equal diameters.

The side member 36 has an extension I3I mounted thereon (Figure 1) and the side member 34 has an extension I32 mounted thereon (Figure 2). The extension I3I carries a bearing I34 and the extension I 32 carries a bearing I35 in alignment therewith. A shaft I33 is journaled in the bearings I34, I35. A sprocket I36 is secured to the right end of the shaft I 33 as viewed in Figure 11 and is connected in driven relation to the sprocket I39 by means of a roller chain I31.

The sprocket I38 secured to the left end of the shaft I33, as viewed in Figure 11, has a roller chain I39 passing thereover and adapted to drive a sprocket I49 carried on a shaft I4I, which will presently be described.

The shaft I33 carries a collar I42 working against the face of the bearing I35 and a collar I43 working against the face of the bearing I34 to prevent any end play on the shaft I33.

A cam I44 is secured to the shaft I33 and functions to lower the knife for cutting the strip material at the proper time in the machine cycle, as will presently be described. A similar cam I45 is secured to the shaft I33 and acts in concert with the cam I44 for moving the knives.

The extension I3I (Figure 11) has a vertical slot I46 formed therein and the extension I32 has a vertical slot I 41 formed therein. A knife support body I48 has a tongue I49 on one end thereof slidably mounted in the slot I46 and a similar tongue I59 on the other end thereof slidably mounted in the slot I41.

The knife support body has upwardly projecting ears I5I and I 52 spaced apart from each other, and a roller I53 is pivotally mounted therebetween on a pivot pin I54.

The roller I 53 cooperates with the cam I44. Likewise ears I55 and I56 have a roller I51 supported therebetween on a pivot pin I58, the roller I51 being provided to cooperate with the cam I45.

The knives are suitably journaled in the knife support body I48, the method of mounting the same being identical. An example of this is shown in Figure 6, where the body I48 carries bearings I59 and I69 which form journal supports for a knife shaft I6I which has a portion I62 of reduced diameter.

The rotary knife I63 between fittings I64 and I65 is clamped against a shoulder I66 by means of a nut I61. A collar I68 eliminates end play on the shaft I6I and a grooved pulley I69 mounted on the shaft I'6I serves to drive the same.

The second knife, referring now to Figure 5, is designated by the numeral IN. The shaft carrying this knife is designated by the numeral I12 and this shaft carries a double grooved pulley I13. A belt I14 connects one step of the double pulley I13 to the larger step of the pulley 24 on the motor, suitable free idler pulleys I15 and I16 (Figures 1, 3 and 4) being provided. for effecting a right-angle drive. A belt I11 passing around the other step of the double pulley I 13 serves to drive the pulley I69.

The knife support body I48, as hereinbefore described, has tongues I49 and I59 which engage the slots I46 and I41, respectively. The knife support body hassockets I18 and I19 (Figure 11) formed therein which are engaged by the upper ends of the springs I80 and I8I,'respectively The lower ends of: the springs engage sockets I82 and I83 formed in a crossmember I84 extending between the extensions I3I and I32. Thus the springs I80 and I8I normally urge the knife support carriage I48 upwardly and thereby maintain the rollers I53 and I51 in contact with the surfaces of the cams I44 and I45 respectively. g

' When the shaft I33, carrying the cams I44 and I45, is rotated, the cams acting against the rollers I53 and I51 cause the carriage I48 to move downwardly and thereby bring the rotary cutting knives I63 and Ill through the paths of the paper strips.

It will be understood that the knives rotate continuously and are merely shifted across the paths of the paper strips by the action of thecams I44 and I45, and thenallowed to rise to their normal positions as the rollers I53 and I51 encounter the lower portions of the cams.

The shaft I85, referring to Figure 8, has one end I86 thereof journaled in a bearing I81 secured to the side member 36. The shaft I85 also has a reduced portion I88 which is journaled in a sleeve shaft I89. The sleeve shaft I89 is in turn journaled in a bearing I90 secured to the side member 34. The shaft I85 may have formed integral there'- with a fluted roller I9I having a midportion I92 of reduced diameter. The sleeve shaft I89 may also have formed integral therewith a fluted roller I93, the midportion I94 of which is of reduced diameter. A shoulder I95 formed integral with the shaft I85 is of such length as to define the spacing between the fluted rollers I9I and I93. The sleeve shaft shoulder I98 formed thereon and operatively positioned in contact with the side of the bear-- end portions 203 and 204, respectively, on the shaft 205, shown in Figure '14, and also Figure 5.

The shaft 205 may have formed integral there with a fluted roller 206, the mid-portion 201 of which is of reduced diameter. The shaft 205 has a portion 205 which is rotatable independently thereof. The portion 205 may have formed integral therewith a fluted roller 208, the mid-portion 209 of which is undercut or grooved.

The portion 205 also has a shank 2I0 which forms a working fit in a hole 2| I formed in the shoulder 2I2 of the shaft 205. Suitable means maybe provided for retaining the shank 2I0 in the hole 2II. The length of the shoulder 2I2 defines the spacing between the fluted rollers 206 and 208, somewhat like the arrangement I05, I88, described above and shown in Figure 8, the corresponding shoulder being I95, and this length is preferably the same as that of the shoulder I95 between the fluted rollers I9I and I93 with which the fluted rollers 206 and 208 cooperate. Due to the fact that the bearings 203 and 204 are mounted in slots, the fluted rollers automatically assume positions in accord- I89 has a ance with the character of the work and the material used.

The bearing I81 has an extension 2I3 formed integral therewith (see Figures 1, 5 and 8), and

this extension has a vertical slot 2I4 formed therein. The bearing I has a similar extension.2l5 formed'integral therewith and having a vertical slot 2I8 formed therein (Figures 2,5and8).

The shaft 2| 1 has one end 2I8 of reduce diameter and rotatively mounted in the slot 2 I4;

and its other end 2I9 of reduced diameter and rotatively mounted in the slot 2 I Ii.

A flanged roller 220 is secured to the shaft M1 by means of a set screw 22I, and its flanges are spaced apart a distance equal to the width of thefluted rollers plus suitable clearance; and the flanged roller 220 cooperates with the fluted roller 206. r 1

' A second flanged roller 222 is mounted on the shaft 2I1, and is secured thereto by means of a set screw 223; and the roller 222 cooperates with the fluted roller 208.

A crank arm 224 has a bearing 225 in one end thereof journaled on the shaft I4I adjacent to the side member 34, and a second crank arm 226 has a bearing 221 journaled on the shaft I4I adjacent to the side member 38 (Figure 5). The other ends of the crank arms 224 and 226 pivotally support a shaft 228 which may have formed integral therewith fluted rollers 229 and 230. The crank arm 224 is provided with a boss 23I (Figures 6 and '1). The boss 23I is slotted, and a rod 232 has its lower end flattened and positioned in the slot. A pivot pin 233 serves to pivotally connect the rod 232 to the boss 23I; the rod 232 is threaded and by means of a nut 234 the tension of the spring 235 may be adjusted.

Likewise, the crank arm 226 is provided-with a. boss 236 which is slotted to contain the flattened end of a rod 231, a pin 238 serving to pivotally connect the rod 231 to the slotted boss 236. The rod 231 is threaded and the nut 239 is provided for adjusting the tension of the spring 240.

The extension I 32 of the side member 34 is provided with a horizontally projecting lug 24I having a hole therein through which the threaded rod 232 passes. v

The upper end of the spring 235 rests against the lower surface of the lug 24! and, as aforesaid, the nut 234 may be adjusted so as to set the tension of the spring against the crank arm 224 to any desired final pressure.

The feeding device includes mechanism shown A stud 248 has a threaded in Figures 9 and 12. end 241 engaging a boss formed in the side member 34 and a portion 248 of reduced diameter. A crank arm 249 has a hub portion 25I which forms a working fit on the portion 248. A second crank arm 252 also bears on the portion 248 and members up with th end of .the hub 250,

being secured thereto by means of screws one of;

The extension I3Iv of the side member 38 has a horizontally project-' ing lug 242 through which the threaded, rod 231 which is shown at 253. A washer 254 secured to the end of the portion 248 by means of a cap screw 255 serves to rotatively retain the arm 249, the hub 25I, and the arm 252 on the portion 248.

A gear 256 has a ratchet wheel 251 secured thereto by means of screws, one of which is designated by the numeral 258. The gear 256 and the ratchet wheel 251 have a common center and are bored out and provided with a bushing 259 which forms a working fit on the outer surface of the hub 25 I A gear 268 has secured thereto a ratchet wheel 26I by means of screws, one of which is designated by the numeral 282. This gear and ratchet wheel also have a common center and are provided with a bushing 263 which also forms a working fit on the outer surface of the hub 25 I.

By this arrangement, the crank arms can be moved rotatively on the portion 248 of the stud 246; and the gear and ratchet wheel 256, 251, and the gear and ratch 268, 26I, may be independently rotated on the hub 25 I.

A shaft 264 supported by the crank arms 249, 252, has pivotally supported thereon a pawl 265 having a hub 266. A spring 261 has one end thereof engaging a hole in the hub 266, and the other end 268 thereof engaging the pawl 265 and urging it into engagement with the teeth of the ratchet wheel 26I. The shaft 264 also carries a pawl 269 having a hub 218 and a spring 21I, one end of which engages a hole in the hub 218, and the other end 212 of which engages the pawl 269 and urges it toward the teeth of the ratchet wheel 251.

A spacing member 213 is positioned on the shaft 264 between the pawls. The shaft 254 projects beyond the side of the crank arm 249 and is pivotally connected to a bar 214. The bar 214 is provided for moving the'crank arms 249 and 252 through definite and settable arcs, as will be described, and in so doing cause the gears 256 and 260 to advance a definite distance.

Since the gear 256 meshes with the gear I91, the sleeve shaft I89 (referring now also to Figure 8) causes the fluted roller I93 to rotate through a predetermined cycle. The gear 268 meshes with the gear I99, and therefore when it moves under the urge of the ratchet 265 the shaft I85 is rotated, and with it the fluted roller I9I.

The bar 214, as can be seen in Figure 2, is provided with a plurality of holes 215. A bar 216 (see Figure 18 also) is bossed and mounted on a shaft 211 carried in a bearing boss 293 in the side member 34, and a bearing boss 294 in the side member 36.

The bar '216 is likewise provided with a series of holes 219 like the holes 215. A pin member 219 may be inserted in any hole in the bar 214 and thence passed into any hole in the bar 216 and thereby the amount of feed is adjusted. For example, if the pin 219 were inserted in the hole 215 in the bar 214 nearest to the crank arm 252, and were then matched with the hole 218 nearest the pivotal point of the bar 216, the feed would be a minimum because the radius from the first hole 218 to the pivot 211 is the shortest available radius of the bar 216; and likewise, the radius from the first hole 215 in the bar 214 to the shaft 264 is the shortest available radius of the bar 214.

The bar 2'56 carries a yoked ei'rtension 288 in the yoke of which is mounted a roller 2'8i pivoted on a shaft 232. The cam #24 acting against the roller 285, moves the bar 2'56 on its pivot 211 and as the roller 29i engages a high point on the cam I24, the bar 21'6 swings in a counter-clockwise direction, as viewedin Figure 2, and due to the linkage 219 between the bars 216 and 214, the crank arms 249 and 252 are likewise moved in a counterclockwise direction, as viewed in Figure 2. This causes the pawls 265 and 269 to respectively move the ratchet wheels 26I and 25I in a counterclockwise direction, as viewed in Figure 2. The gears secured to the ratchets in turn rotate the gears I99 and I91 and thereby rotate the fluted rollers 229 and 238, as described above.

A spring 283, having one end connected to the outer end of the bar 216 and the other end connected to a frame member 284, serves to maintain the roller 28I in contact with the surface of the cam I24.

A shaft 285 has one end pivotally mounted in the side member 34 and the other end pivotally mounted in the side member 36. This shaft projects beyond the side member 34 and has secured thereto a crank arm 286. See Figures 5 and 6 also. The end of the crank arm is bifurcated and pivotally supports a roller 281 on a pivot pin 288. This roller cooperates with a cam 289 carried on the shaft I4I.

A spring 298, having one end connected to a projecting member 2! on the crank arm 286, and having its other end connected to a stud 292 on the side member 34, serves to maintain the roller 281 in contact with the cam 289 so that as the shaft I4I carrying the cam 289 rotates, the shaft 285 will rock on its bearings.

Mounted on the shaft 285 is a block 295. The block 295 has a hole formed therein which fits on the shaft 285, and a set screw 296 positively secures the block to the shaft 285. A second hole 291 is formed in the block 295 at right angles to the shaft 285 and a pipe 298 is mounted in the hole 291 and is secured therein by means of a set screw 299.

The pipe 298 has on its left end, as viewed in Figure 6, a tubular portion 388 at right angles thereto. The ends of the tubular portion are capped and a plurality of holes, one of which is designated by the numeral 38I, are formed therein. The left end of the pipe 298 is flexibly connected to a pipe 382 by means of a rubber hose or other flexible connection 383 (see Figures 1 and 5).

The pipe 382 is connected to one end of a valve 384, and the other side of the valve connects to a pipe 385 which is in turn connected to a source of air under pressure.

The valve 384, provided for turning on or shutting off the air, is preferably of the plunger type and has a plunger 381 which is actuated by the cam I I5 on the shaft 32, which turns the air on at a definite time in the machine cycle, maintains the valve in its open position during a definite number of degrees of the cycle and closes said valve. The blast of air through the openings 381 is utilized to facilitate the application of the working surface material to the outer surfaces of the drawing rollers 258, which will presently be described. I j

A T 988 in the pipe 385 has a pipe 389 connected thereto which leads air to a plunger valve 3 I 8 having a plunger 3I I which is actuated by the cam 59 on the shaft 32 (Figures 4 and 6). A pipe 3I2 leads air from the plunger valve 3I8 to the horizontal pipe 398 which has apertures or holes 399 formed therein, through which blasts of air may pass, as will hereinafter be described.

Referring now to Figures 1, 2, 3, and 4, the side plate 3 I3 has a slot 3 I4 formed therein which forms a bearing for one end of a shaft 3I5. A

second side plate 3I6 likewise has a slot 3" formed therein to support the other end of the shaft 3I5. The shaft 3I5 is provided for supporting reels 3I8 and 3I9, which in turn carry rolls of the strip material to be applied to the surfaces of the drawing rollers. For purposes ofthis description, the strip material on the reel 3I8 is designated by the numeral 328, and the strip material on the reel 3I9 is designated by the numeral 32I.

The side plate 3 I 3 has a slot 42I formed therein which carries one end of a shaft 322 and one end of a shaft 323, and the side plate 3I6 has a slot 324 formed therein which supports the other ends of the shafts 322 and 323, The shaft 323, as may be seen in Figure 4, carries rollers 325 and 326; theshaft 322 carries rollers 321 and 328.

A suitable weight 329 in the slot 42I, and a similar weight 338 mounted on the slot 324, bear against the shaft 322 and thereby urge the rollers of this shaft into intimate contact with the rollers on the shaft 323 so that when the strip material is threaded between the adjacent rollers, the weight serves to prevent the strip material from being fed off of the reels too rapidly.

The side plate 3I3 is provided with a vertical slot 33I which supports one end of a shaft 332, and a similar vertical slot 333 in the side plate 3I6 supports the otherend of the shaft 332.

Mounted on the shaft 332 are drums 334, 335. r

The vertical slot 336 is formed in the side plate 3I3 and provided with side members 331, 338, forming slides. Slidably mounted on said slides is a. bearing block 339 which pivotally supports one endof a shaft 349, and the other end of the shaft 340 is carried in a bearing block 343, supported in slides 344 and 345 carriedon the side plate 3I6. The shaft 348 carries drums 34I and 342.

The side plate 3 I 6 has secured thereto an angle member 345, and this angle member is in turn secured to one leg of an L-shaped member 346. and the other leg of the L-shaped member is secured to the vertical leg 284 of an L-shaped member mounted on the side member 34.

Similarly, the side plate 3I3 has secured thereto a leg or member 348 which is in turn secured to the horizontal leg of an L-shaped member 349, and in turn the vertical leg of the L-shaped member 349 is secured to the vertical leg of an L-shaped member 356. The horizontal leg of the latter is secured to the upper surface of the side member 36.

A tie rod 35I, extending-between side plates 3| 3 and 3 I 6, serves to tie them together in spaced relation to each other.

A cross rod 352, extending from the side plate 3l3 tothe side plate 3I6, pivotally supports one end of a pressure arm 353. The pressure arm bears, against the strip material 32I carried on the reel 3I9. The pressure arm 353 has secured thereto a bar 354 and by means of a weight 355 slidably-mounted on the bar 354, the pressure exerted by the arm 353 against the strip material on the reel may be adjusted and a set screw 356 in the weight 355'may be tightened to secure the. weight in any adjusted position on the bar 354.

A second pressure arm 35! has one end thereof pivotally mounted on the cross rod 352 and is provided to bear against the strip material 326 on the reel 3I8. Secured to the pressure arm 351 isa bar 358 adjustably carrying a weight 359, which in turn hasa set screw 360 for securing it in any set-portion on the bar 358.

' path defined by the cam member 365, which path The discharge.

A cross bar 36I, extending from one side plate to the other, forms a support for one edge of a pan or the like 362. A second cross bar 363, parallel to the bar 36I, forms a support for the other edge of the pan 362 which is provided for containing a supply of liquid adhesive material 364.

The strip material, which is preferably formed of parchment paper, as it leaves the reel 3I8, passes between the rollers 321 and 325, and thence passes over the drum 34I carried on the shaft 340 (Figure 2).

The strip material 32I, in passing over the drum 34I, receives an adhesive coating on its lower surface due to the fact that'the drum- 335, carried on the shaft 332, rotating in a counterclockwise direction (as viewed in Figure 2) picks up the adhesive 364 from the body and delivers it to the drum 34I, with the result that the lower surface of the material 320 passing over this drum receives a coating of adhesive.

Likewise, the strip material 32I passes between roller 328 on the shaft 322, and roller 326 on the shaft 323, and thence over the drum 342, which is supplied with adhesive by the drum 334.

The strips of material leaving the drums MI and 342 pass into the mechanism and are applied to the surfaces of the drawing rollers 259.

In Figure 6, it will be seen that the strip material 32I passes under the flanged roller 228, over the fluted roller 266, and thence between the fluted roller 206 and the fluted roller I9I passing underneath the fluted roller I9I and between the fluted roller 229 and the surface of the draw.- ing roller 258. The drawing roller 250 rotates in a clockwise direction, as viewed in Figure 6, and a stream of air passing through the holes 30I impinges against the end of the strip and holds the same in contact with the surface of the drawing roller when the strip is started on to the drawing roller. The stream of air follows up the beginning and the end of the strip due to the fact that the pipe 298 is swung downwardly by the cam 289, and insures that the beginning of the strip is properly engaged by the fluted roller 9 I.

In the present embodiment, two-and-one-half turns of parchment strip is wound on or applied to the surface of the drawing roller.

The knives, one of which is indicated at I63 as previously described as rotating continuously, are moved downwardly by the cam I45 acting against the roller I51 carried on the knife-sup-' port I48. As the knife moves downwardly, it engages and severs the strip 32I after which the knife immediately rises to its normal position, the machine continues to run until the severed end passes the fluted roller 229 and the fluted roller 9|.

As the strip material is finished off on the drawing roll, the Geneva movement advances the finished roller toward the position F, and consequently advances the drawing roller 258 toward the position S, the drawing roller 25II having been fed into the turret, in a manner to be presently described.

As the finished drawing roller 250 is advanced toward the position F, it encounters a camming member 365 which causes the drawing roller to rise out of the supporting slot 81 and follow the terminates in a discharge chute. chute may consist, referring also to Figure 5, of a member 366 of L-shaped cross section, and a second member 38'! also of L-shaped cross sec-.

tion, held in spaced relation to each other by means of cross members 368.

The upright leg 366 of the L-shaped member 366 clears the shafts of the drawing rollers, and the horizontal leg 369 forms a support at one end of the drawing roller shaft. Likewise, the upright portion 361 clears the other end of the drawing roller shafts, and the horizontal portion 391 forms a support for the drawing roller shafts at the other ends thereof.

Midway between the members 399 and 361 is a bar 369 preferably of square cross section, above which the shafts between the two drums of each roller pass.

The finished drawing rollers, as stated before, are cammed out of the turret by the camming member 355, and then they roll down the discharge chute just described.

Referring now to Figure 3, the inner end of the discharge chute is supported as follows: The inner end of the L-shaped member 366 is secured to a bar 319, the end of which is engaged by a bolt 31! passing through the side member 36.

The L-shaped member or track 361 ha secured thereto a rod 312, the end of which is engaged by a bolt 313 passing through the side member 34.

A chute or track for the drawing rollers to be covered is generally designated by the numeral 314 and includes the L-shaped track members 315, 316 (see Figure 4), held together in spaced relation by cross tie members 311. Midway between the track members 315 and 315 is a bar 318 preferably of cross section which is adapted to extend between the pairs of drums on the drawing rolls and yet clear the shafts therebetween.

The inner end of this track is secured to the frame as follows: The rail 315 has secured thereto a bar 319, the outer or left end (as viewed in Figure 4) being secured to the side member 34 by means of a cap screw 389. Likewise the rail 316 has a bar 33! secured thereto, and a cap screw 382 passing through the side member 36 threadedly engages this rod.

Referring to Figure 14, which illustrates the action of the mechanism for feeding drawing rolls to the turret, a bar 383 extends from the side member 34 to the side member 36,. and is secured to said side members by means of bolts such as the bolts 394, the ends of the bar being turned at right angles to accommodate said bolts.

A block 335, having a rectangular hole 386 formed therein, is secured to the bar 383 by means of cap screws, one of which is shown at 381.

A rectangular feed bar 399 is reciprocably mounted in the rectangular hole or slot 385. This feed bar has its lower end bifurcated and a roller 389 is supported therein on a pivot p n 399. A spring 396 has its lower end connected to a pin 391 in the block 395, and its upper end connected to the drawing roll engaging member 39| carried on the upper and of the bar 388. This spring urges the bar 338 downwardly and holds the roller 399 in contact with the cam 59.

The drawing roll engaging member 39! has its upper surface 392 angular with respect to the axis of the bar 388, and this surface 392 normally clears the shafts of the drawing rolls on drawing roll 259 (positioned in the turret 86, Figure 14) is being finished off, the drawing roll 259 is in position in the succeeding stage of the turret to be advanced to the upper position by the action of the Geneva movement. How.- ever, prior to attaining that position, the drawing roll 259 was in the position now occupied by the drawing roll 259 The drawing roll 259 advanced from the position 259 to the position 251". after which the feed bar 283 due to the action of the cam 58 was raised to the position shown in dotted lines at 259 It will be noted that the upper edge of this drawing roll when so raised is up near the severed end of the strip material 321 and this abets the stream of air passing through the apertures 399 from the pipe 398 in the guiding of said severed end between the fluted pressure roller 229 and the drawing roll which is at the operative position in the turret.

As the cam 58 is rotated, the feed rod 338 is again lowered thereby, bringing the shaft of the drawing roll to the position 259 which is closely adjacent to the surface of the turret slot 88 so that when the drawing roll 259 is moved from the operative stage, the turret picks up the roll from the position 259 and moves it to the operative position 259. As this occurs, the next succeeding drawing roll in the position 259* rolls on to the surface 392 of the feed device and the process just described is repeated as the strip material 32| is applied to the drawing roll in the operative position 259.

A boss 499 formed on the side member 34 is threadedly engaged by a shouldered screw 49L Pivotally supported on the screw 49! is an arm 492 which carries on its lower end a shoe 493, the surface of which is normally tangent to the drawing rollers on the track 314. The end 493 of this shoe is curved to form a camming surface so that the drawing rollers rolling down the track 314 may engage the camming surface 493 and raise the lower end of the arm 492, and the end 4 93 is also curved upwardly to cam off of the last drawing roller leaving the tracks. By this action the arm 492 is gently lowered as the last drawing roller leaves the track 314. i

Secured to the arm 492 is a bracket 494 which supports thereon a mercury switch 495, the terminals 496 of which may be connected in the circuit of the motor 23. As the last drawing roll leaves the track 314, the surface 493 of the shoe 493 cams off of this roller and permits the end of the arm 492 to move downwardly, thereby. causing the mercury in the switch 495 to move to the right end of the mercury switch 495 and thereby uncover the contacts and open the motor circuit. This stops the machine from operating until an attendant places more drawing rollers on the track 314.

A stop pin 491 in the boss 499 is engaged by the arm 49?. as it moves downwardly and thereby the lowest position of the arm 492 is defined. This movement need only be sufficient to actuate the mercury switch 495.

As these drawing rollers pass down the track toward the lower end thereof, the foremost one engages the camming surface 493 raises the end of the arm 492, and thereby rocks the mercury switch to its normal position with the mercury again bridging the contacts therein. This enables the motor circuit so that the machine will again operate.

Since the average drawing roll has two drumlike portions, and since this description has set forth how the machine applies, for example, two and one-half turns of parchment strip material to the surface of one of these drums, it must be understood that both drums of the drawing roller are covered simultaneously by strip material 32! from the reel 318, and the strip material 329 from the reel 3l9.

The cam 59 is so timed and is of such shape that it effects the application of blasts of air via the orifices 399 in the pipe 398 to both of said strips for causing them to properly start on to the drawing roll at the operative stage of the turret.

The cam H5 is so shaped that it effects the supplying of blasts of air to the ends of the strips which are being finished off at the proper time via the orifice 3M in the pipe 300, and this pipe is moved up and down by the action of the cam 289 to facilitate the finishing off operation.

Figure 15 shows a typical drawing roller 250 after the working surfaces have been removed and conditioned to have new working surfaces applied thereto. 7

Figure 16 is similar to Figure 15, except that the drawing roll has had working surfaces 320 and 32! applied thereto, and this drawing roll is thereby conditioned to be used in drawing frames, etc., in which said rolls are to be used.
